Design a database table structure that meets the following business requirements?

I was stumped by the last question in today's interview: (original picture) Design a database table structure that meets the following business needs: 1. A certain merchant holds a lottery for playing games for a period of time. Only users who play the game with 50 points or more can win the lottery. Each user can participate in multiple events. 2. After the event, a list of lottery records needs to be compiled, including the following: 3.

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
